The TI-1706+ got again a rounder shape and different keys compared to the earlier TI-1706 III introduced six years earlier.
An identical housing in different colors was used with both the TI-106
and TI-1722+ calculator.
Dismantling this TI-1706+ calculator manufactured in November 1993 by Nam Tai Electronics, Inc. in China reveals a clean design centered around an unknown single-chip calculator circuit bonded in Chip-on-Board (COB) technology directly onto a double-sided printed circuit board (PCB) and powered by four solar cells.
Inspecting the PCB of this TI-1706+ calculator brought our attention to two small marks reading TI-106 and DA312 confirming its relationship to the TI-106. We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
Within three years the design of the calculator was changed, don't miss the next generation of the TI-1706+.
